Abstract

A machine for washing or drying laundry, having a stationary part, a tub, a drum rotatably accommodated in the tub, and a drive motor. The drive motor comprises a stator or housing component connected to the machine, a rotor having a rotor shaft connected with the drum, and bearings arranged in the stator or a housing component, and the rotor shaft is rotatably mounted by the bearings. One or more spring or damping elements connects the stator or housing component to the stationary part.

First claim

What is claimed is:

1 . A machine for washing or drying laundry, comprising:
a stationary part; a tub; a drum rotatably accommodated in the tub; a drive motor comprising:
a stator or housing component connected to the machine;
a rotor having a rotor shaft connected with the drum; and
bearings arranged in the stator and or housing component and the rotor shaft is exclusively rotatably mounted by the bearings; and
one or more spring or damping elements connects the stator or housing component to the stationary part.

2 . The machine according to claim 1 , further comprising a bellows connecting the stator or housing component with the stationary part of the washing machine.

3 . The machine according to claim 2 , wherein the tub is accommodated in a stationary part.

4 . The machine according to claim 2 wherein the spring or damper comprises a spring-damper system and the stator or a housing component is connected with the stationary part via the spring-damper system, and with the tub via the bellows.

5 . The machine according to claim 1 wherein the stator has coils that can be fed with current, and the rotor has permanent magnets.

6 . The machine according to claim 5 , wherein the stator comprises a stator ring that supports the coils, and the stator ring is arranged on the housing component.

7 . The machine according to claim 6 , wherein the stator ring is manufactured from a thermally and/or electrically resistive material in an injection-molding process.

8 . The machine according to claim 1 , wherein the bearing is respectively accommodated in the stator and in the housing component.

9 . The machine according to claim 8 , and further comprising a hub, accommodating the bearing, and integrated into the stator or into the housing component and into an additional housing component.

10 . The machine according to claim 9 , wherein the stator or the housing component accommodating the stator and the additional housing component are respectively designed in a pot shape and are connected with one another in the region of their end walls.

11 . The machine according to claim 10 , wherein the stator is arranged in confronting relationship to the drum.
